TO ALL WHO M It MAY CONCERN:

Be it known that we, REUBEN FINK and Jason B.-HEB.SHOCK, of Lancaster, in the county of Lancaster,

and State of Pennsylvania, have invented certain new anduseful Improvements on Thin-Couplings for shafts .or vehicles; andwe declare that the following is a full and clear description of the construction and operation of thesame, reference being had to the accompanying drawings, making apart of this specification, in which- Figure 1 shows our improvement combined with the ordinary thill,,-the shaft down.

Figure 2, a perspective view of the same, with the shaft thrown vertically and held in place.

Figure 3 shows the several parts in detail, and detached. I

The object of our invention is, like that of other devices employed for the purpose, to provide a means to support the shafts of vehicles in a perpendicular position when raised up out of theway, as is frequently made necessary, and to prevent rattling in the same while driving.

' The drawings so clearly show the' construction and application of our invention as to require only a simple,

statement to enable any one skilled in the art to make and use the same. i

It consists in the addition (to the ordinary clip) of two pieces, A and B, hinged together at a, fig. 3. The piece A is secured by a screw-bolt below the shaft-arm of the ordinary clip-coupling, as shown by figs. 1 and 2. The other portion, B, of the pieces or two parts, hinged as aforesaid, has an open notch, 15, and is passed through a slot, H, in the projecting end of the bed-plate c of the clip, which. embraces the axle or bed I. This prolonged slotted portion is slightly inclined, and surrounded by a coiled spring, D, to bear up against the notched tongue or piece 13, in order to hold the same in place, and also to prevent rattling. I

The operation is simple. In ordinary driving, the position is shown by fig. 1. When the shafts are ele- I vated, the pieeeB slides upwards through the slot H, and iszlocked in the notch b, as shown by fig. 2, and in this position supports the shafts vertically or even when inclined backwards against the vehicle, but will not prevent the shafts from being turned down by asimple pull on either of them. The spring yields readily.

We are aware that springs are used on clips and thin-couplings with the same object. in view; nor do we claims. thill-coupling clip or spring, as such are common. I But we are not aware that any application has been made heretofore of hinged pieces attached and operated for that purpose in the manner shown and described.

What we claim as our invention, and desire to secure by Letters Patent, is- 1. The combination of the hinged pieces A 13, arranged and entering the slotted prolongation of thc bedplate 0, substantially in the manner and for the purpose specified.

I 2. In combination with the piece A, hinged at a to the notched piece 13, the bed-plate a, when prolonged and furnished with a slot, H, and coiled spring D, arranged and operating substantiallyiin the manner and for the purpose described.
